Chileans love kids, and family-friendly lodging and kid's specials are the rule, not the exception. Many hotels feature playgrounds, swimming pools, child care, and attached rooms or space for additional beds, and some resorts offer full-scale kids' activities, giving parents a breather and a little "adult time." Few, if any, hotels (such as luxury hotels) refuse children, but be sure to check their policy anyway when booking.
When choosing lodging, check to see if a suite is cheaper than booking two connecting rooms. Most suites have a sofa bed, or at the very least the hotel can add an extra cot-style bed. A good bet for families spending several days in a destination is an apart-hotel or a cabaña, which are self-catering units with living areas and kitchens -- these options are frequently less expensive than a hotel room. Hotel chains such as the Radisson and the Sheraton occasionally offer specials for families with kids, but as a general rule, kids are either free when sharing a room with their parents, or are charged a minimal fee for an extra bed.
